  | I've got vague recollections from the distant past under Solaris
  | or (less likely) Digital Unix, of having a setting (an environment
  | variable set in the equivalent of .bashrc) that made all
  | backgrounded jobs "nohup-ed".
  | 
  | Am I imagining it? Is the a bash way of doing that? Is there any
  | decent documentation on nohup? The man page is miserably
  | inadequate.

 `stty -hup' perhaps?:  no SIGHUP is sent on
                 last controlling tty close.

 `trap "" 1' perhaps?:  any SIGHUP is ignored by the
                 shell and all subsequent children.

  neither is exactly the same as nohup(1) since
  `nohup' also redirects stdout and/or stderr
  (if they are the controlling(?) tty) to a file
  besides ignoring SIGHUP; the above only either
  preclude the usual case of SIGHUP or simply
  ignore any SIGHUPs.  and both of the above
  effect more than backgrounded pipes.

  my own vague recollection is the C-shell (csh(1))
  had something like what is being asked about (I
  don't recall what, I've always Hated `csh'), but
  I cannot recall anything like that for any(?) of
  the Bourne-ish shells.
 
cheers!
